Garmin G3x Wiring Questions

[Shadowrider]

Next question. Seems like I read somewhere in the 900 page manual, does the G3x need permanent 12v power?

Well that's a new one to me. I don't have that. Hope I don't need it. I'm not quite ready to turn everything on yet. Another week or two.

I think is saves configuration and it has a clock so I am pretty sure you need it?

They are the same pins as Dsub pins. You need a Dsub pin crimping tool, similar to this:

Just Google Dsub crimping tool and you can watch a video on how it is used.

Yes I have that tool. These have different pins than all the rest of the connectors? Garmin only gave 4 of them so I was wondering if these are solder pins. My elt I tried to crimp with this tool and the male dsub would not hold the wire on because the wire was so small of wire I had to solder them.

Yes. I guess I worded my question poorly. I used the GTX to GTR20 interconnect drawing. It shows music out form the G3x (pins3 9 20) and music in from 19 18 37. I was wondering what this is for? Read more and found this is if you opt for the xm music. It comes from the G3X. Audio alerts come form mono G3x out to the mono GTR20 in.

So I am going to disconnect pins 3 9 20 and hook those to audio jack that goes into my ipad. Audio alerts will still work over the wire I ran from the G3X pin 1 and 18 to pins 32 31 on the GTR20.
